Regular exercise is one of the best things you can do for your health. It has many benefits. It can improve your overall health and fitness and reduce your risk for many chronic diseases. To get the most benefit, here's how much physical activity you should get:

For adults

Get at least 150 to 300 minutes of moderate-intensity or 75 to 150 minutes of vigorous-intensity aerobic physical activity each week. Or you could do a combination of the two:

• Try to spread your physical activity out over several days of the week. That's better than trying to do it all in one or two days.
• Some days you may not have long blocks of time to do physical activity. You can start slowly and break your exercise time into chunks. Even small amounts of exercise can be helpful.
• Aerobic activities include walking fast, jogging, swimming, and biking.
• Moderate intensity means that while you are doing that activity you should be able to say a few words in a row but not sing.
• Vigorous intensity means that while you are doing that activity, you won't be able to say more than a few words without stopping for a breath.

Also, do strengthening activities two or more days per week:

• Strengthening activities include lifting weights, working with exercise bands, and doing sit-ups and pushups.
• Choose activities that work all parts of your body your legs, hips, back, chest, stomach, shoulders, and arms. For each exercise, try repeating the movement 8 to 12 times. As you get stronger, work up to doing 2 or 3 rounds of each exercise for the best results.

If you are an older adult, you may also benefit from a combination of activities that include aerobic exercises, strength or resistance training, and balance training. Balance training such as walking heel-to-toe or standing on one leg may help improve stability and prevent falls. Before you start exercising, check with your health care provider to determine the best type or amount of activity for you based on your fitness level and health.

For preschool-aged children (ages 3-5)

Preschool children should be physically active throughout the day, to help with their growth and development:

• They should get both structured and unstructured active play. Structured play has a goal and is directed by an adult. Examples include playing a sport or a game. Unstructured play is creative free play, such as playing on a playground.
• Encourage active play with a variety of activities.

For children and teens

Get 60 minutes or more of physical activity every day. Most of it should be moderate-intensity aerobic activity:

• Activities should vary and be a good fit for the child's age and physical development
• Moderate-intensity aerobic activities include walking, running, skipping, playing on the playground, playing basketball, and biking

As part of the 60 minutes or more of daily physical activity, try to do each of these at least 3 days a week: vigorous-intensity aerobic activity, muscle-strengthening activity, and bone-strengthening activity:

• Vigorous-intensity aerobic activities include running, jumping jacks, and fast swimming
• Muscle-strengthening activities include playing on playground equipment, playing tug-of-war, and doing pushups and pull-ups
• Bone-strengthening activities include hopping, skipping, jumping jacks, playing volleyball, and working with resistance bands

Older adults, pregnant women, and people with chronic health problems

Older adults, pregnant women, and people who have disabilities or special health needs should check with their provider on how much physical activity they should get and what types of activities they should do.

Exercise tips

People who are trying to lose weight may need to get more physical activity. They also need to adjust their diet, so they are burning more calories than they eat and drink.

If you have been inactive, you may need to start exercising slowly. You can keep adding more gradually. The more you can do, the better. But try not to feel overwhelmed and do what you can. Getting some physical activity is always better than getting none. Even small increases in exercise can benefit your health.
